Фізична географія та геоморфологія. 2017. Вип. 2 (86). С. 59-66.УДК 551.4(477)https://ir.library.knu.ua/handle/15071834/9029Проаналізовано особливості виникнення та поширення зоогенних форм рельєфу створених комахами на території Українського полісся. Зокрема, досліджено такі зоогенні форми рельєфу, як різні за механічним складом мурашники; норні гнізда ос, бджіл і джмелів; нірки та підземні тунелі хрущів, піраміди деревоточців тощо. Охарактеризовано розміри таких форм рельєфу та щільність їх розташування у межах окремих ділянок дослідженої території.It is hardly possible to imagine zoogenic morphosculpture of Ukrainian Polissia without the relief forms created by insects. While constructing their accommodation and creating favourable conditions for hunting, they relocate significant volumes of soil and plant remnants. This results in appearance of accumulative and denudation micro-, nano- and pico-relief forms. Research into relief forms of these types allows to estimate the role and scale of influence that insects have on creation of morphosculptural peculiarities of the presented region. Analysis of peculiarities of appearance and spread of zoogenic relief forms within the Ukrainian Polissia area enables to highlight the leading role of ants among the insects, which participate in creating relief forms. They create both positive and negative zoogenic relief forms. During the fieldwork on key points of Nizhyn and Borzna districts in Chernihiv Oblast and Olevsk and Yemilchyne districts in Zhytomyr Oblast we discovered overground and underground anthills, ant trails and underground galleries created by ants. Differences in mechanical composition of the overground part of a hill allow to divide anthills into the next groups: 1) soil (ground), 2) soil-litter (which consist of soil basis and forest litter, namely twigs, leaves, bark, needles, dry grass, etc.), 3) in some cases, litter (which consist almost entirely of forest litter). The vast majority of anthills within the specified area are soil anthills, which, in most cases, are approximately 14-15 cm high and 25-30 cm in diameter. Usually slopes of such anthills are gentle. During the fieldwork it was also discovered that the underground part of anthills, regardless of their type, is frequently of a greater size than the overground one. Excavation materials enable to confirm that ant paths and cells can reach a depth of 2 m. Moreover, on certain points of the investigated area (for instance, in the forest near Hryshivka village in Borzna district, Khvylivka village in Nizhyn district and some others) only underground anthills occur. Unfortunately, it is quite difficult to determine morphometrical indicators of these constructions and it is virtually impossible to measure the length of underground galleries created by ants. Thus, results of fieldwork only revealed that certain cells of such anthills are situated at a depth of 2 m. In comparison with ants, other species of insects play insignificant role in creation of surface of the investigated area. Admittedly, fires have considerable influence on morphological and morphometrical peculiarities and mechanical composition of anthills as well as on relief forms created by other insects.ukПоліссямурашникимурашині стежкипідземні галереїґрунтові мурашникидіаметрвисотакамериходинориPolissiaanthillsant trailsunderground galleriessoil anthillsdiameterheightcellspathsholesСтаття
